Sawtooth Traverse

Weather is about as cooperative as late April gets in the Sawtooths. Today is your best day — mostly sunny, 42°F, nearly calm at 6 mph SW. Tonight drops to 26°F with a slight chance of snow showers (19%), and that pattern repeats through the trip: daytime highs in the low 40s, overnight lows in the upper 20s, and scattered snow shower chances ramping up to 48% by Monday. None of these events look significant — light dustings are more likely than accumulation — but plan your high camp and exposed ridge segments for Saturday afternoon or early Sunday morning before the shower activity increases. The nearly-calm winds (2-8 mph throughout) mean no meaningful wind chill concern on the ridges.

Snowpack is relevant here. The SNOTEL picture shows 37 inches of depth regionally, and the Long Lake station (840 ft — note the suspiciously low elevation for a SNOTEL, but 95 inches and 39.7 SWE is real depth) is on a falling trend, consistent with normal April consolidation and melt, not a rapid loading event. At traverse elevations you can expect continuous snow coverage with a soft, settled surface by midday on sun-exposed aspects. Morning travel on north-facing slopes will be firm — microspikes or an ice axe are worth having for the steeper traverses above 8,000 ft during the early hours before solar softening. The overnight refreeze to 26°F guarantees a crust each morning.

Stream crossings are not a concern this trip. All five gauges are running 87-118% of median with no flows approaching the 150% threshold. The mild daytime highs (42°F) will drive some afternoon snowmelt at elevation, but overnight temps well below freezing shut that cycle down hard each night — you won't see a runoff spike building over the trip. Cross drainages in the morning if you have a choice; afternoon flows will be slightly higher but still well within normal range.

No active fires within 50 miles and nearly calm, variable winds mean air quality is clean. Nearly 14 hours of daylight gives you a long operating window — sunrise at 6:42 AM, sunset at 8:37 PM. Use Saturday's clear window to make miles on the exposed high terrain, and treat Sunday/Monday as shoulder days where you build in flexibility for the shower windows. This is a good trip.
